Since setting a clip is mandatory for almost all widgets, we can as well change the size-allocate signature to include a out_clip parameter, just like GtkCssGadget did. And since we now always propagate baselines, we might as well pass that one on to size-allocate. This way we can also make sure to transform the clip returned from size-allocate to parent-coordinates, i.e. the same coordinate space priv->allocation is in.
